Pressure Control Solenoid "G" Circuit Short to Ground or Open

While the vehicle is being driven so that gear changes occur, a short to ground or open is detected in the solenoid (SL4) valve circuit for 1 second (1-trip detection logic).
  • Solenoid (SL4) valve
  • Transmission wire
  • Harness and connector
  • ECM

DTC stored

SAE Code:

P2814

MONITOR DESCRIPTION

This DTC indicates an open or short to ground in the solenoid (SL4) valve circuit. The ECM commands gear shifts by turning the solenoid valves on or off. When there is an open or short in any solenoid valve circuit, the ECM detects the problem, illuminates the MIL and stores a DTC.

The ECM performs the fail-safe function and turns the other normal solenoid valves on or off. In the case of an open or short circuit, the ECM stops sending current to the open or shorted solenoid.

CONFIRMATION DRIVING PATTERN

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.

HINT:

  • After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
  • When clearing the permanent DTCs, refer to the Clear Permanent DTC procedure.

  1. Connect the Techstream to the DLC3.
  2. Turn the engine switch on (IG) and turn the Techstream on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the engine switch off and wait for 2 minutes or more.
  5. Turn the engine switch on (IG) and turn the Techstream on.
  6. Start the engine.
  7. Perform the D Position Shift Test inspection in Road Test. [*1]

    [*1] : Normal judgment procedure.

    The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

  8. Stop the vehicle.
  9. Enter the following menus: Powertrain / Transmission / Utility / All Readiness.
  10. Input the DTC: P280714.
  11. Check the DTC judgment result.

    Techstream Display

    Description

    NORMAL
    • DTC judgment completed
    • System normal

    ABNORMAL
    • DTC judgment completed
    • System abnormal

    INCOMPLETE
    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    N/A
    • Unable to perform DTC judgment
    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    HINT:

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
